Howdy, could use a bit more info, like carb, EFI, MPI

Is this a new to you boat?
If not new, how did it do last season?

Just need some onfo as to how it was doing previously and what might have caused this

Have a engine serial number?

Thanks for the serial number
Its TBI so that reduces so of the things to look for

It has EST ignition,so look for 12V on the coil when ifnition is turned ON and not cranking?
When cranking the motor, does the tachometer show any kind of reading and looking for around 300 rpm?

If the above to are met, then check the distributor as shown
